Abstract

A machining program for controlling a numerical control machine tool is edited by a machining program editing function of a numerical control apparatus. Machining step division codes and machining step identification codes are input, and machining step unit programs are defined by dividing the machining program on the basis of machining step division blocks. Machining step identification codes are extracted for each of the machining step unit programs and are defined as the machining step names of the machining step unit programs. The machining step names are displayed on a screen according to the sequence of the execution of the machining step programs. Locations of the machining step names are changed according to externally input commands. The sequence of the execution of the machining programs is converted according to the thus changed locations of the machining step names.
